Play safe and one-shot mechanics contradiction

I don't understand, GGG wants us to play safe because of the very harsh death punishments, but it seems there are thousands way to be one-shot in the game, and lots of them are barely seeable or ridiculously unavoidable.
Sometimes, I feel as if my character is bullied by the game's unfair mechanics, like on death effects, overtuned white mobs, difficult trials/sanctums, etc. That's not fun at all for me as a casual player.
Maybe I'll take a break and wait for the next major patch.
